1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Safety of 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea

Abstract: This study evaluated the occurrence of PPCPs in Cau River (Vietnam). Surface water and sediment samples were collected to determine PPCP concentrations The anal. results showed the presence of 36 out of 56 investigated PPCPs in samples. The total concentration of PPCPs in water samples ranged from 8.21 to 529 ng/L and the value observed in sediment was from 17.4 to 172.8 渭g/kg. Along the Cau River, there was a trend of accumulation of PPCPs at the downstream. The highest level of PPCP was observed after the river flows through Thai Nguyen and Bac Ninh provinces. Among detected PPCPs, the ones detected with high frequency (over 70%) and high concentration were caffeine, sulfamethoxazole, and lincomycin in water and triclocarban, levofloxacin, and griseofulvin in sediment. The water-sediment partition coefficient (Kd) was estimated to explore the fate of PPCP in the river, and the observed Kd mean values for lincomycin, sulfamethoxazole, and griseofulvin were 223.0, 7.6, and 997.0 kg/L, resp. Risk assessment was initially conducted by applying a semi-quant. assessment risk quotient (RQ); the potential ecol. risk to the aquatic organism of PPCPs posed a moderate risk. In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Safety of 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea).
